l Tol all wo'm r't may concern:

Bel it known@ that 1,-1onpanoGnMivrRie, a' citizenv orv che United!States, residing at South Pasadena, in the county of Los Angeles',-State of California, have invented1 new and useful improvements in'Concrete- Mi-Xergof which the following isV a specification'.

This invention relates to concretev mixers and the principal object isto provide a com crete mixer of the street paving? type with a pluralityof conveyors to li'tt the various materials from the ground level to bedelivered into elevatedA measuring hoppeis. llt is also an object toprovide a concrete mixer with independent chutes'to convey thediii'erent ingredients' that com-pose the concrete, and' operate eachindividually or cooperatively as desired.

It is also ail-[object to*A provide means for measuring a certain amountof ingredients in an elevated position and under the control of a singleoperator to be delivered to a common delivery hopper. f

It is a further object to provide means'fo'r folding. a portion of theendless conveyers occupying a position next to the' ground' level',together with a movable measuring bon by means of which Sina-llquantities can' be measured from the elevated hoppers as desired.

In the drawings accompanying this specification,` Figure l yis anelevationshowing the applicationof the invention to an ambulatoryconcretemixer. Fig. 2" is a side ele-V` vation of a' portion of' amovable concrete mixer, showing the invention ap lied thereto.v Fig; 3'is a front elevation o I 'the mixer,

showingI the endless conveyers and the-means for driving the same. Fig;4' is a` section on the line 4 4 of'Fig: 2 viewed in the directionindicated by the arrows, the section be#y ing' through the elevatedhoppers and the platform adjacent thereto and the driving shaft of theprime mover'. Fig. 5 is a perspective view of the elevated measuringhoppers with their dischargel gates into the maan chute or hopper,together with the auxiliary measuring box.- Fig;v 6'. is a detail ysection on the line 6--6 of Fig. 5, viewed in i necessitating thepresence of a large number of laborers at this' point to bring theproper materials for the mixture, together with the delay indeliveringthe material should one or the other of the ingredients be more remotefrom the mixer or a mistalrebe made by the materialE man and hishandlers, and with these large movable skips greater danger is incurredof their falling with the heavy weight and injuring the workmen.

This invention overcomes the above diicultie's in that the materials aredeposited in rows onthe ground level by the dump wagons and shoveledinto the lower hoppers without the use of'wheel barrows and elevated byconveyers incapable of falling to injure the men seriously, and thecontrol of the mixing operation can be performed by one man who isstationed on a platform adjacent the elevated measuring hoppers, who ata'll times has complete control over the conveyers and an unobstructedview ot all theI operations of the machine. 1 j,
